Figure 23. 3D View Figure 24. Virtual Cockpit www.maximintegrated.com Figure 25. Numeric Display Maxim Integrated 12 MAX21000 Maxim Inertial Demo (MInD) Evaluation Kit Macro A macro is a set of commands that can be executed through the selection of its identifier. The macro feature provided by the software permits the user to run an existing macro, record a new one, and save the current configuration as a macro. Each macro is composed of two functions: play and pause. The play button on the Macro management section of the toolbar (see the Toolbar section) triggers the execution of the play function; the Pause button triggers the execution of the pause function. The macro to be executed can be selected using the drop-down list in the Macro management section. To play a macro: Select the desired macro from the Select the macro drop-down list in the Macro management section of the toolbar. Click the Play button in the Macro management section of the toolbar to execute the play function of the macro. Click the Pause button in the Macro management section of the toolbar to execute the pause function of the macro. Recording a macro means that every write operation executed using the Tabs frame is saved in a macro. Note that the write operation executed using the Direct commands tool are not recorded. To record a macro: Open the Macro menu. Click on the Record a macro menu entry. Insert the name of the new macro in the dialog window and click OK. If a valid name is set, the recording starts. If the name is not valid, an error message appears and the name is requested again. Execute all the write operations you want to store. Open the Macro menu. Click on the Record a macro menu entry to stop the recording. When the recording is terminated, all the write operations are stored in the play function of the created macro. To recall the recorded macro, select it from the Select the macro drop-down and click the Play button. www.maximintegrated.com Evaluates: MAX21000 Gyroscope The macro feature also permits the user to save the current status of the registers in a macro. To save the current register's status as a macro: Open the Macro menu. Click on the Save as macro... menu entry. Insert the name of the new macro in the dialog window and click OK. If a valid name is set, the register status is saved in a new macro. If the name is not valid, an error message appears and the name is requested again. The Macro management tool also provides an interface to manage the macros. The Advanced macro manager interface permits the user to manually create a new macro, edit, modify, or delete an existing macro, and to check the syntax of a macro. A macro in the MInD software is a set of instructions written in a Javascript-like language. Almost all the basic instructions of Javascript are provided, so refer to a Javascript reference guide for a list of available instructions. To add the software functionalities, a new object called mind has been integrated. This object provides the following functions: ReadRegister(<device name>, <bank address>, <register address>) : returns a register value; WriteRegister(<device name>, <bank address>, <register address>, <data to write>) : write a value on a register; print(<string to print>) : prints the specified string in the Output text area. Some other external functions could be released together with the software; you can find their definition in the utilfunc.js file on the root installation folder. Currently, only the sleep(time) function is provided; it introduced a delay of time ms in the execution. For an example of code, see Figure 26. To open the Advanced macro manager: Open the Macro menu. Click on the Advanced macro manager menu entry. Figure 26 shows the Advanced macro manager interface. The interface is composed by a toolbar on the top that provides all the functionalities of the Advanced macro manager, the list of available macros on the left, a text editor to show the macro content on the right, and a debugging output text area on the bottom. Maxim Integrated 13 MAX21000 Maxim Inertial Demo (MInD) Evaluation Kit The toolbar offers the following functionalities (from left to right): Create a new macro: Creates an empty macro and adds it on the list of available macros. Save the current macro: Saves the currently edited macro. Delete a macro: Deletes the currently selected macro. Check macro syntax: Checks if the syntax of the currently edited macro is correct. Figure 26 shows an example of macro, which increments the value of the SENSE LOW PASS BW field of the SENS_CFG_1 register every 500ms. Note that the behavior of the Play button of the Advanced macro manager is different from the behavior of the Play button of the main window, in that it executes the script as is, without calling a specific function; so, if you want to debug a function you have to call it inside the code (as shown in the example). When the debugging is complete, you should delete the call instruction. Evaluates: MAX21000 Gyroscope Maxim Integrated strongly suggests that you write your code inside a play or pause function, in order to permit the execution from outside the Advanced macro manager. Logging The logging feature permits the user to save the captured data from the MInD device to a desired text file. The logging options are available by clicking on the Logging menu at the top of the GUI window (Figure 27). Clicking on the Configure menu entry allows the user to select the destination file for the logging information and the fields to be saved on the destination file, as shown in Figure 28. Clicking on the Start/Stop menu entry allows the user to enable/disable the logging on file. Note: If you are planning to execute a long-time logging, it is suggested to keep the 3D view closed (see the Troubleshooting section for details).
